README

Automatic store/website code matcher for multi-store Magento 2 / Adobe Commerce setups based on HTTP_HOST.

Overview

This Composer package automatically sets the correct Magento store or website code based on the incoming HTTP_HOST header, eliminating the need to manually configure store matching in pub/index.php.

Features

• Zero configuration - Works automatically after installation
• Performance optimized - Stores/Websites can be cached by opcache (static array in app/etc/store-hosts.php)
• Local overrides - Support for environment-specific configuration
• Composer autoload - Uses standard Composer autoload mechanism

Installation

1. Run the following Composer command in your Magento 2 / Adobe Commerce project root:

composer require hryvinskyi/magento2-store-matcher

The post-install script will automatically create app/etc/store-hosts.php and app/etc/store-hosts.local.php if they don't exist.

Configuration

Main Configuration

Edit app/etc/store-hosts.php to define your store and website host mappings:

return [
    'store' => [
        'default' => ['www.example.com', 'example.com'],
        'french' => ['fr.example.com', 'french.example.com'],
        'german' => ['de.example.com', 'german.example.com'],
        // ... more stores
    ],
    'website' => [
        'base' => ['www.example.com'],
        'europe' => ['eu.example.com'],
        // ... more websites
    ],
];

Local Overrides

For environment-specific configuration, create app/etc/store-hosts.local.php:

return [
    'store' => [
        'default' => ['test.example.test', 'localhost'],
        'en_store' => ['en.example.test'],
    ],
];

This file will be automatically merged with the main configuration and can be gitignored.

How It Works

1. Composer's autoload mechanism loads src/autoload.php on every request
2. The autoload file checks if running in web context (not CLI)
3. It calls StoreMatcher::match() which contains all the matching logic
4. The matcher loads configuration from app/etc/store-hosts.php
5. It modifies $_SERVER with PARAM_RUN_TYPE and PARAM_RUN_CODE
6. Magento bootstrap uses these values to determine the store/website

Requirements

• PHP >= 8.1
• Magento 2.4+
